A process for the dehydrogenation of alkyl-containing compounds comprises reacting an alkyl-containing compound and a Group VI nitrosyl complex characterized as a transition metal complex having the composition Cp'M(NO)(R1)(R2), wherein Cp' is selected from certain substituted and unsubstituted η5-cyclopentadienyl groups; M is W or Mo; and R1 and R2 are independently selected from CH2C(CH3)3; CH2Si(CH3)3; CH2(C6H5); CH3; hydrogen; and η3-allyl; provided that if R1 is hydrogen, R2 is η3-allyl; under conditions such that the alkyl-containing compound is converted to an olefin, and in particular embodiments, a terminal olefin. The dehydrogenation can be carried out using a neat and/or undried alkyl-containing compound and/or may be conducted under air, and does not require a sacrificial olefin to drive the reaction, thereby increasing convenience and decreasing cost in comparison with some other dehydrogenation processes.
一种去氢化含烷基化合物的方法包括将一种烷基化合物与一种被表征为具有组成Cp'M(NO)(R1)(R2)的过渡
金属配合物的第六族亚硝基复合物反应,其中Cp'从某些取代和未取代的η5-
环戊二烯基团中选择;M为W或Mo;R1和R2分别从 C(
CH3)3;
CH2Si( )3;
CH2(
C6H5); ;氢;和η3-烯丙基中选择;条件是如果R1为氢,则R2为η3-烯丙基;在这些条件下,烷基化合物被转化为烯烃,特别是末端烯烃。该去氢化可以使用纯净和/或未干燥的烷基化合物进行,和/或可以在空气中进行,并且不需要牺牲性烯烃来推动反应,从而增加了便利性并降低了成本,与其他一些去氢化过程相比。
